| Smart home system intends to improve people's living quality and make home more comfortable, secure and efficient by using advanced technologies. With the development of information technology, the internet technology plays a more and more important role in almost all fields of people's life. So it is possible to connect all home inner devices into the internet and control them through the internet. The network smart home has become an important direction of the development of smart home.Embedded system is based on application-centered hardware design and software development facing application. Embedded system is widely applied in such areas as manufacture, process control, communication, instrument, and consumer product. The development of Internet is causing the demand of integration of embedded and Internet.eCos comes out from 1998 to now, it has developed into one of the fastest growing real-time operating systems in the embedded marketplace in eight year. It is a new embedded operating system that has several outstanding strongpoint such as free source code, oriented small or middle scale application, preemptive kernel, configurability, multitask and preferable portability. It has been used in all kinds of embedded systems.At first the paper introduces the framework, function and developing trend of smart home, then analyzes the present smart home controller in detail. Secondly, based on detailed analysis of S3C44B0X processor and eCos, the hardware and software design scheme of embedded development system are completed independently. As for hardware design, the detailed construction and function description of every hardware component are given. As for the software design, the configuration and compilation of standard eCos are described in detail. The hardware and software design of embedded development system based on S3C44B0X processor and eCos are completed eventually. Finally, based on the eCos, the embedded Web server LibHTTPD is ported and the application software is...
